| Abstract: | This paper deals with the studies of 2D NMR spectra of disaccharidc moiety of a flavonol-3-O-α-L-rhamnopyranosyl-α-L arabofuranoside from the leaves of Artabotrys hexapetalus. The interlinkage of the biose was determined to be α-L-rhamnopyranosyl-(1→2)-α-L-arabofuranose.A simple NMR criterion was proposed for flavonol-3-O-rhamnopyranosyl (1 → 2)-arabofuranoside. |
